Description

Die Erfindung betrifft eine Matratze, ein Kissen oder dergleichen.
Matratzen, Kissen und dergleichen sind in der Praxis bekannt und bestehen im allgemeinen aus einer sackähnlichen Umhüllung, der Überzug, und einem darin angebrachten Füllmaterial. Der Überzug weist eine Füllöffnung auf, durch die während des Verfahrens zur Herstellung der Matratze das Füllmaterial angebracht wird, worauf die Füllöffnung abgeschlossen wird, in der Regel mit einem Reißverschluß. Eine derartige Matratze ist in US-A-4 445 241 beschrieben. Bei dieser Matratze ist der Überzug jedoch aus luftdichtem Material hergestellt. Der Überzug ist daher nicht dampfdurchlässig. Zwar heißt es in der US-Veröffentlichung, daß der Reißverschluß vom wasserdichten Typ ist, aber die Art und Weise, wie diese Wasserdichtheit erhalten wird, ist nicht beschrieben. Weiter sind im Überzug Öffnungen angebracht, die den Überzug ungeeignet machen, um maschinell gewaschen zu werden. Vor der Benutzung wird in der Regel auf der Matratze ein Bettlaken oder dergleichen angebracht, während um ein Kissen ein Kissenbezug angebracht wird. Ein derartiges Bettlaken oder Kissenbezug bildet dann die direkte Kontaktfläche zwischen dem Benutzer und der Matratze oder dem Kissen und kann einfach abgenommen werden, um gewaschen zu werden.
The invention relates to a mattress, a pillow or the like.
Mattresses, pillows and the like are known in practice and generally consist of a sack-like covering, the covering, and a filling material attached therein. The cover has a filling opening through which the filling material is applied during the process for the manufacture of the mattress, whereupon the filling opening is closed, usually with a zipper. Such a mattress is described in US-A-4,445,241. However, the cover of this mattress is made of airtight material. The coating is therefore not breathable. Although the U.S. publication states that the zipper is of the waterproof type, the manner in which this waterproofness is obtained is not described. Furthermore, openings are made in the cover which make the cover unsuitable for machine washing. Before use, a bed sheet or the like is usually attached to the mattress, while a pillow case is attached to a pillow. Such a bed sheet or pillow case then forms the direct contact surface between the user and the mattress or pillow and can simply be removed for washing.

Inbesondere im Gesundheitswesen, wie zum Beispiel in Krankenhäusern, besteht ein Bedürfnis und manchmal sogar eine Notwendigkeit, Betten zu waschen, zum Beispiel wenn ein Krankenhausbett von einem Patienten geräumt wird und für einen nächsten Patienten gebrauchsfertig gemacht werden soll. Dabei muß auch die Matratze gewaschen werden. Das kann mit der Hand geschehen, was aber ziemlich arbeitsintensiv ist. In particular in healthcare, such as in Hospitals, there is a need and sometimes even a need to wash beds, for example if a Hospital bed is cleared by a patient and for a next patient is made ready for use should. The mattress must also be washed. That can done by hand, which is quite labor intensive is.

Die vorliegende Erfindung bezweckt im allgemeinen, eine verbesserte Matratze zu beschaffen.The present invention generally aims to: to get an improved mattress.

Ein erster besonderer Zweck der vorliegenden Erfindung ist daher die Beschaffung einer Matratze, die in hohem Maße geeignet ist, maschinell gewaschen zu werden.A first particular purpose of the present invention is therefore procuring a mattress to a high degree is suitable for machine washing.

Es ist natürlich möglich, bestehende Matratzen in einer Waschstation oder Waschstraße maschinell waschen zu lassen. Bestehende Matratzen haben jedoch mehr oder weniger das Problem, daß beim Waschen Flüssigkeit über die genannte Füllöffnung in das Innere der Matratze eindringen kann. Diese eindringende Flüssigkeit, die an sich schon das Füllmaterial in dem Überzug angreifen kann, ist eine potentielle Quelle für das Einführen und Wachsen von Mikroorganismen wie Bakterien und Schimmel. Es wird klar sein, daß dies aus hygienischer und medizinischer Sicht unerwünscht ist.It is of course possible to have existing mattresses in one Have the washing station or car wash machine washed. Existing mattresses have more or less that Problem that when washing liquid over the above Filling opening can penetrate into the interior of the mattress. This penetrating liquid, which in itself is that Filling material in the coating can attack is one potential source for the introduction and growth of Microorganisms such as bacteria and mold. It becomes clear be that this is hygienic and medical is undesirable.

Es ist daher ein weiterer Zweck der vorliegenden Erfindung, eine Matratze zu beschaffen, deren Füllmaterial in hohem Maße vor Flüssigkeit geschützt ist.It is therefore another purpose of the present Invention to procure a mattress, the filling material is highly protected from liquid.

Eine andere, an den Überzug einer Matratze gestellte Anforderung ist, daß dieser gut dampfdurchlässig ist. Im Gebrauch soll die Matratze nämlich in der Lage sein, den vom Schlafenden herrührenden Wasserdampf aufzunehmen und an die Umgebung abzugeben, weil sonst die Außenseite der Matratze naß vom Schweiß des Benutzers werden würde: die Matratze soll atmen können.Another, placed on a mattress cover The requirement is that it is well breathable. in the The mattress should be able to use the mattress To absorb sleeping water vapor and to the Surrender environment, because otherwise the outside of the mattress would get wet from the sweat of the user: the mattress should be able to breathe.

Um die genannten Nachteile bekannter Matratzen zu überwinden und die genannten Zwecke zu erreichen, ist eine Matratze der obengenannten Art erfindungsgemäß dadurch gekennzeichnet, daß der Überzug aus einem Tuch hergestellt ist, das keine Flüssigkeit, wohl aber Dampf durchlassen kann, und daß die Füllöffnung durch einen an dem Überzug befestigten Abdeckstreifen eines Materials abgedeckt ist, das Flüssigkeit nicht, wohl aber Dampf durchlassen kann.To the mentioned disadvantages of known mattresses overcome and achieve the stated purposes is one Thereby mattress of the above type according to the invention characterized in that the cover is made from a cloth is that no liquid, but steam let through can, and that the filling opening through one on the coating attached cover strip of a material is covered, the liquid cannot, but steam can let it through.

Die Befestigung des Abdeckstreifens an dem Überzug kann durch zum Beispiel Leimen oder Schweißen stattfinden. The cover strip can be attached to the cover for example by gluing or welding.

Bevorzugt ist der Abdeckstreifen mit einer spritzwasserdichten Öffnung versehen, um Luft passieren zu lassen, so daß Luft aus dem Inneren der Matratze entweichen kann, wenn auf die Matratze ein Druck ausgeübt wird, wenn eine Person darauf Platz nimmt.The cover strip with a splashproof opening to allow air to pass leave so that air can escape from inside the mattress can if pressure is applied to the mattress if a person sits on it.

In einer weiteren bevorzugten Ausführungsform der Matratze gemäß der vorliegenden Erfindung sind Verbindungsnähte zwischen verschiedenen Teilen des Überzugs geschweißt. Dadurch wird die Verwendung von Steppnähten, über die Wasserinfiltration stattfinden könnte, vermieden.In a further preferred embodiment of the Mattress according to the present invention Connection seams between different parts of the cover welded. This eliminates the use of quilting, over the water infiltration could be avoided.

Die obengenannten Probleme gelten auch für vergleichbare Gegenstände wie zum Beispiel ein Sitzkissen oder ein Kopfkissen, und die durch die Erfindung vorgeschlagene Lösung ist auch auf derartige Kissen anwendbar. Im Rahmen der vorliegenden Anmeldung wird daher unter dem Ausdruck "Matratze" auch jeder beliebige andere Gegenstand verstanden, der aus einem gefüllten Überzug besteht, wie zum Beispiel ein Sitzkissen oder ein Kopfkissen.The above problems also apply to comparable objects such as a seat cushion or a pillow, and that by the invention proposed solution is also on such pillows applicable. Therefore, in the context of the present application any other under the term "mattress" Understand the object of a filled coating such as a seat cushion or a Pillow.

Die genannten und anderen Aspekte, Merkmale und Vorteile der vorliegenden Erfindung werden durch die nachfolgende Beschreibung einer bevorzugten Ausführungsform einer erfindungsgemäßen Matratze verdeutlicht, unter Hinweis auf die Zeichnung, in der:

  • Figur 1 schematisch eine perspektivische Ansicht einer bekannten Matratze zeigt;
  • Figur 2 schematisch einen Querschnitt der Matratze nach Figur 1 zeigt;
  • Figur 3 schematisch einen mit Figur 2 vergleichbaren Querschnitt einer Ausführungsform einer erfindungsgemäßen Matratze zeigt;
  • Figur 4 schematisch eine perspektivische Ansicht eines Abdeckstreifens zeigt; und
  • Figur 5 schematisch eine perspektivische Ansicht einer erfindungsgemäßen Matratze nach Figur 3 in einer zum maschinellen Waschen geeigneten senkrechten Stellung zeigt.
  • The above and other aspects, features and advantages of the present invention are illustrated by the following description of a preferred embodiment of a mattress according to the invention, with reference to the drawing, in which:
  • Figure 1 shows schematically a perspective view of a known mattress;
  • Figure 2 shows schematically a cross section of the mattress of Figure 1;
  • Figure 3 shows schematically a cross section comparable to Figure 2 of an embodiment of a mattress according to the invention;
  • Figure 4 shows schematically a perspective view of a cover strip; and
  • FIG. 5 schematically shows a perspective view of a mattress according to the invention according to FIG. 3 in a vertical position suitable for machine washing.
  • In den Figuren sind gleiche oder vergleichbare Teile mit gleichen Bezugsziffern bezeichnet.The same or comparable parts are shown in the figures designated with the same reference numerals.

    Zur näheren Klarstellung der Erfindung zeigt Figur 1 schematisch eine Matratze 1 mit einem im allgemeinen schachtelförmigen Äußeren. Das heißt, daß die Matratze 1 nach Figur 1 eine untere Fläche 2, eine obere Fläche 3, kurze Seitenflächen 4 und 5, die ein Fußende und ein Kopfende bestimmen, und lange Seitenflächen 6 und 7 besitzt, wobei alle genannten Flächen im wesentlichen die Form eines Rechteckes aufweisen. Eine derartige Form ist jedoch zur Anwendung der Erfindung nicht notwendig. Beispielsweise kann die Matratze abgerundete Formen aufweisen oder sogar ganz kreisförmig ausgeführt sein. Die Erfindung ist jedoch gleichermaßen auf ein Kissen anwendbar. Ein Sitzkissen eines Rollstuhles weist im allgemeinen eine Form auf, die der in Figur 1 dargestellten Form der Matratze 1 entspricht. Ein Kopfkissen für ein Bett weist jedoch bekanntermaßen eine gewölbtere Form auf, wobei das Kissen in Draufsicht eine einem Rechteck gleichende Form, jedoch in Seitenansicht eine einem Oval gleichende Form aufweist. Man könnte sagen, daß dann die vertikale Abmessung der Seitenflächen 4, 5, 6, 7 fast auf Null reduziert ist. Auch runde Kissen sind jedoch möglich. Die Erfindung ist bei allen genannten Gegenständen und Formen anwendbar, die hier kurz mit dem Ausdruck "Matratze" bezeichnet werden.FIG. 1 shows a further clarification of the invention schematically a mattress 1 with a generally box-shaped exterior. This means that the mattress 1 1 a lower surface 2, an upper surface 3, short side surfaces 4 and 5, the one foot end and one Determine the head end and has long side faces 6 and 7, where all the surfaces mentioned are essentially in the form of a Rectangle. Such a form is, however Application of the invention is not necessary. For example the mattress has rounded shapes or even whole be circular. However, the invention is equally applicable to a pillow. A seat cushion one Wheelchairs generally have a shape that the in Figure 1 corresponds to the shape of the mattress 1 shown. On However, pillows for a bed are known to have one arched shape, with the pillow in plan view a shape similar to a rectangle, but a side view has an oval shape. You could say that then the vertical dimension of the side surfaces 4, 5, 6, 7 is reduced almost to zero. Round pillows are also, however possible. The invention is in all the objects mentioned and forms applicable, here briefly with the expression "Mattress" to be called.

    Die Matratze 1 umfaßt eine geschlossene Umhüllung 10, der Überzug, der mit einem geeigneten Füllmaterial 9, zum Beispiel Schaumkunststoff, gefüllt ist.The mattress 1 comprises a closed covering 10, the coating, which with a suitable filler 9 to Example foam plastic, is filled.

    Beim Herstellen der Matratze 1 wird zuerst die Umhüllung 10 aus einem oder mehreren Blättern gebildet, die auf solche Weise aneinander befestigt sind, daß die Umhüllung 10 die gewünschte Form erhalten hat. Figur 1 zeigt schematisch, daß dabei mindestens eine Verbindungsnaht 11 gebildet ist. Bei einer bekannten Matratze 1 ist die Verbindungsnaht 11 als Steppnaht ausgeführt.When manufacturing the mattress 1, the first Envelope 10 is formed from one or more sheets that are attached to each other in such a way that the Envelope 10 has received the desired shape. Figure 1 shows schematically that at least one connecting seam 11th is formed. In a known mattress 1 Connection seam 11 designed as a quilted seam.

    Zum Anbringen des Füllmaterials 9 in der Umhüllung 10 ist beim Herstellen der Umhüllung 10 eine Füllöffnung 12 frei gelassen. Um nach dem Anbringen des Füllmaterials 9 in der Umhüllung 10 das Schließen der Umhüllung 10 zu ermöglichen, ist die Füllöffnung 12 mit einem Schließorgan 13 versehen, wofür normalerweise ein Reißverschluß verwendet wird.For attaching the filling material 9 in the casing 10 is a filling opening 12 when the casing 10 is produced released. To after the filling material 9 in the wrapping 10 closes the wrapping 10 enable, is the filling opening 12 with a closing member 13 provided, what normally uses a zipper becomes.

    Als Alternative könnte die Matratze 1 dadurch hergestellt sein, daß um ein geeignetes Füllmaterial 9, zum Beispiel eine Kunststoffschaumplatte, die Blätter der Umhüllung 10 "drapiert" und aneinander befestigt sind.As an alternative, the mattress 1 could thereby be produced that a suitable filler 9, for Example of a plastic foam sheet, the leaves of the Envelope 10 "draped" and attached to each other.

    In der Privatsphäre besteht nur selten ein Bedürfnis nach dem Waschen, d.h. Naßreinigen, der Matratze. Es gibt aber Gebrauchssituationen, in denen ein Bedürfnis oder manchmal sogar eine Pflicht besteht, Matratzen häufig zu reinigen. Beispiele derartiger Situationen sind die Verwendung in Krankenhäusern, Pflegeheimen, Gefängnissen usw., in denen eine Matratze von mehreren aufeinanderfolgenden Benutzern verwendet wird und/oder eine größere Gefahr läuft, verschmutzt zu werden. Das Bedürfnis nach Waschen ist nicht lauter durch hygienische Erwägungen eingegeben; auch um bakterielle Infizierung folgender Benutzer zu vermeiden, muß das ganze Bett und also auch die Matratze gereinigt werden.There is rarely a need for privacy after washing, i.e. Wet cleaning the mattress. There are but use situations in which a need or Sometimes there is even an obligation to mattress frequently clean. Examples of such situations are Use in hospitals, nursing homes, prisons etc., in which a mattress of several successive users is used and / or one there is a greater risk of becoming dirty. The need after washing is no louder due to hygienic considerations entered; also bacterial infection following To avoid users, the whole bed and therefore the must Mattress to be cleaned.

    Eine wichtige, an eine Matratze gestellte Anforderung ist, daß das Überzugsmaterial flüssigkeitsbeständig, d.h. flüssigkeitsundurchlässig ist. Dagegen soll das Überzugsmaterial jedoch dampfdurchlässig sein. Andererseits kann das Überzugsmaterial auch richtig feuerfest sein. Es ist jetzt in der Praxis schon ein Material bekannt, das diesen Anforderungen genügt. Wie mehr im einzelnen im Ausschnitt nach Figur 2 erläutert ist, besteht dieses Material aus mindestens zwei Schichten. Eine Trägerschicht 21 wird durch ein Trikotgewebe einer Kunststoffaser wie Nylon gebildet. Diese Trägerschicht 21 verteilt dem Überzug Eigenschaften wie Festigkeit und Dehnbarkeit. An der Außenseite ist auf der Trägerschicht 21 eine (oder mehrere) dünne hygroskopische Polyurethanschicht 22 vorgesehen, die Flüssigkeit nicht, wohl aber Dampf durchläßt. Da die Art des Überzugsmaterials kein Gegenstand der vorliegenden Erfindung ist und eine Matratze gemäß der vorliegenden Erfindung mit dem bekannten Überzugsmaterial hergestellt werden kann, wird dies nicht näher beschrieben werden.An important requirement for a mattress is that the coating material is liquid resistant, i.e. is impermeable to liquids. Against that However, coating material should be permeable to steam. On the other hand the coating material can also be really fireproof. It a material is already known in practice that meets these requirements. How more in detail Excerpt according to Figure 2 is explained, this exists Material from at least two layers. A backing layer 21 is through a jersey fabric of a plastic fiber like Nylon formed. This carrier layer 21 distributes the coating Properties such as strength and elasticity. At the On the outside there is one (or more) on the carrier layer 21 thin hygroscopic polyurethane layer 22 is provided, the Liquid does not, but steam does let it through. Since the type of Coating material is not an object of the present invention and having a mattress according to the present invention the known coating material can be produced this cannot be described in more detail.

    Obwohl also bei bekannten Matratzen der Überzug 10 an sich geeignet ist, naßgereinigt zu werden, wird dennoch Flüssigkeit in das Innere der bekannten Matratze 1 eindringen können, wo sie das Füllmaterial 9 angreifen kann, wodurch die Lebensdauer der Matratze verringert wird. Auch kann dadurch das Füllmaterial 9 bakteriell infiziert werden. Ein derartiges Eindringen der Flüssigkeit wird über den Reißverschluß 13 erfolgen und, in geringerem Maße, über die Steppnaht durch die Löcher der Steppnaht 11.So although in known mattresses the cover 10 on is suitable to be wet cleaned, nevertheless Liquid into the interior of the known mattress 1 can penetrate where it can attack the filling material 9, which reduces the life of the mattress. Also the filling material 9 can thereby be infected bacterially. Such penetration of the liquid is over the Zipper 13 and, to a lesser extent, on the Quilting through the holes in the stitching 11.

    Wegen dieser Nachteile werden bekannte Matratzen mit der Hand gereinigt. Eine solche Reinigungsmethode ist jedoch arbeitsintensiv, teuer und ziemlich zeitraubend.Because of these disadvantages, known mattresses are used hand cleaned. However, such a cleaning method is labor intensive, expensive and quite time consuming.

    Eine gemäß der vorliegenden Erfindung verbesserte, in den Figuren 3-5 mit der Bezugsziffer 100 bezeichnete Matratze weist diese Nachteile nicht auf und kann also ohne Bedenken maschinell in einer sog. Waschstraße gereinigt werden.An improved according to the present invention in 3-5 with the reference number 100 Mattress does not have these disadvantages and can therefore be without Concerns cleaned by machine in a so-called car wash become.

    Gemäß einem wichtigen Aspekt der vorliegenden Erfindung ist dazu die Füllöffnung 12 spritzwasserdicht abgeschlossen.According to an important aspect of the present invention For this purpose, the filling opening 12 is closed in a water-tight manner.

    In einer der Einfachheit halber bevorzugten Ausführungsform ist dazu über die Füllöffnung 12 ein wasserdichter Abdeckstreifen 110 angeordnet. Dieser Abdeckstreifen 110 kann zugleich die Funktion eines Schließorgans erfüllen, wobei dann der genannte Reißverschluß weggelassen werden kann, aber in der dargestellten Ausführungsform ist der Abdeckstreifen 110 über einen Standard-Reißverschluß 13 angeordnet. Das hat den Vorteil, daß keine Änderungen in bestehenden Anlagen zur Herstellung von Matratzen notwendig sind und daß sogar schon bestehende Matratzen 1 durch das Anbringen eines erfindungsgemäßen Abdeckstreifens 110 verbessert werden können. Preferred in one for simplicity An embodiment is for this purpose via the filling opening 12 waterproof cover strip 110 arranged. This Cover strip 110 can also function as a Fulfill locking device, then the named Zipper can be omitted, but in the The illustrated embodiment is the cover strip 110 arranged over a standard zipper 13. That has the Advantage that no changes in existing systems for Manufacture of mattresses are necessary and that even existing mattresses 1 by attaching a masking strip 110 according to the invention can be improved can.

    Die erfindungsgemäße Verbesserung wird schon erreicht, wenn der Abdeckstreifen 110 über seine ganze Oberfläche an der Matratze haftet, zum Beispiel mittels einer über die ganze Oberfläche des Abdeckstreifens 110 aufgetragenen Leimschicht. Bevorzugt aber läßt der Abdeckstreifen 110 einen Luftkanal 120 zwischen dem Inneren der Matratze 100 und der Umwelt frei, wodurch Luft aus dem Inneren der Matratze 100 über die Füllöffnung 12 bzw. den Reißverschluß 13 und über diesen Luftkanal 120 entweichen kann, wenn auf der Matratze 100 eine Person Platz nimmt. Wäre ein derartiger Luftkanal 120 abwesend, dann könnte die in der Matratze anwesende Luft nicht oder kaum aus der Matratze entweichen, so daß die Matratze sich "wie ein Ballon" anfühlen würde.The improvement according to the invention is already achieved when the cover strip 110 is applied over its entire surface the mattress adheres, for example by means of a whole surface of the cover strip 110 applied Layer of glue. However, the cover strip 110 preferably leaves an air duct 120 between the interior of the mattress 100 and the environment freely, allowing air to flow from inside the Mattress 100 over the filling opening 12 or the zipper 13 and can escape through this air duct 120 when on the mattress 100 takes one person. Would be a such air duct 120 absent, then that in the Air present or hardly air from the mattress escape so that the mattress "like a balloon" would feel.

    In den Figuren ist eine der Einfachheit halber bevorzugte Ausführungsform zum Freilassen eines derartigen Luftkanals 120 dargestellt, wobei der Abdeckstreifen 110 nur an drei seiner Umfangsränder 111, 112, 113 an dem Überzugsmaterial befestigt ist, derart, daß das an dem Überzug 10 haftende Gebiet 115 des Abdeckstreifens 110 die Form eines um die Füllöffnung 12 herum verlaufenden U aufweist. Das zentrale Gebiet 116 des Abdeckstreifens 110 ruht frei auf dem Reißverschluß 13 oder bleibt davon frei. Bei einer derartigen Ausführungsform kann Luft frei den Reißverschluß 13 passieren und über das zentrale Gebiet 116 des Abdeckstreifens 110 und über den vierten, nicht an dem Überzug 10 haftenden Rand 114 des Abdeckstreifens 110 die Umwelt erreichen. Dieser vierte Rand 114 wird hier auch als freier Rand 114 bezeichnet werden.One is in the figures for the sake of simplicity preferred embodiment for releasing such Air duct 120 shown, the cover strip 110 only on three of its peripheral edges 111, 112, 113 on the Cover material is attached such that that on the Coating 10 adhesive area 115 of masking strip 110 Form of a U extending around the filling opening 12 having. The central region 116 of the cover strip 110 rests freely on the zipper 13 or remains free therefrom. In such an embodiment, air can freely Pass zipper 13 and over central area 116 of the cover strip 110 and over the fourth, not on the Cover 10 adhesive edge 114 of the cover strip 110 die Reach the environment. This fourth edge 114 is also called here free edge 114 may be designated.

    Der Abdeckstreifen 110 kann durch Leimen an dem Überzug 10 befestigt werden. Dazu kann zuerst über drei Seitenränder 111, 112, 113 des Abdeckstreifens 110 ein geeignetes Leimmittel aufgetragen werden, worauf der Abdeckstreifen 110 an seiner Stelle auf der Matratze 100 angeordnet wird. Das Auftragen von Leimmitteln über drei verhältnismäßig schmale Seitenränder ist jedoch eine ziemlich komplizierte Handlung. Es wird daher bevorzugt, daß zuerst Leim über die ganze Oberfläche des Abdeckstreifens 110 aufgetragen wird, worauf über die mit Leim bedeckte Oberfläche ein kleinerer Gegenstreifen 117 aus vorzugsweise demselben Material angeordnet wird, wobei der Gegenstreifen 117 das zentrale Gebiet 116 des Abdeckstreifens 110 bedeckt und sich bis zum vierten Rand 114 erstreckt und die drei Ränder 111, 112, 113 des Abdeckstreifens 110 frei läßt, wie Figur 4 deutlich zeigt.The cover strip 110 can be glued to the Cover 10 to be attached. To do this, first over three Side edges 111, 112, 113 of the cover strip 110 suitable glue is applied, after which the Cover strip 110 in place on mattress 100 is arranged. Applying glue over three however, relatively narrow margins is one pretty complicated plot. It is therefore preferred that first glue over the entire surface of the cover strip 110 is applied, followed by the one covered with glue Surface a smaller counterstrip 117 from preferably the same material is arranged, with the counterstrip 117 covers the central region 116 of the cover strip 110 and extends to the fourth edge 114 and the three Leaves 111, 112, 113 of the cover strip 110 leaves free, such as Figure 4 clearly shows.

    Eine alternative Methode zum Anheften des Abdeckstreifens 110 erfolgt mittels eines Schweißverfahrens, wobei dann über die drei Ränder 111, 112, 113 des Abdeckstreifens 110 eine U-förmige Schweißnaht hergestellt wird. Eine derartige Befestigungsmethode ist besonders zuverlässig und kostengünstig durchzuführen. Da das Schweißen von Polyurethanmaterial dem Fachmann an sich bekannt ist, wird hier nicht näher darauf eingegangen werden.An alternative way to pin the Cover strip 110 is made by means of a welding process, then over the three edges 111, 112, 113 of the Cover strip 110 made a U-shaped weld becomes. Such an attachment method is special to perform reliably and inexpensively. Since that Welding polyurethane material to the expert per se is known, it will not be discussed in more detail here become.

    Zum Erzielen einer guten Verträglichkeit mit dem Überzugsmaterial basiert das Material des Abdeckstreifens 110 vorzugsweise auf Polyurethan.To achieve good compatibility with the Cover material is based on the material of the cover strip 110 preferably on polyurethane.

    Eine also gemäß der vorliegenden Erfindung verbesserte Matratze 100 ist insbesondere geeignet, maschinell gewaschen zu werden. Wenn die Matratze 100 beim Reinigen aufgerichtet wird, derart, daß die den Reißverschluß 13 enthaltende Seitenfläche 4 vertikal gerichtet ist und daß der nicht an dem Überzug 10 haftende freie Rand 114 des Abdeckstreifens 110 nach unten gerichtet ist, wird zum Reinigen benutzte Flüssigkeit wie Wasser durch den Abdeckstreifen 110 von der Füllöffnung 12 ferngehalten werden. Das Wasser, das sonst die Füllöffnung 12 erreichen könnte, strömt jetzt an der Außenseite des Abdeckstreifens 110 herunter. Um die abschirmende Wirkung des Abdeckstreifens 110 nach Möglichkeit zu fördern, erstreckt der freie Rand 114 des Abdeckstreifens 110 sich bevorzugt so weit als möglich an dem Reißverschluß 13 vorbei, bevorzugt bis ans Ende der betreffenden Seitenfläche 4 der Matratze 100. So improved according to the present invention Mattress 100 is particularly suitable for machine washing to become. When the mattress 100 erects while cleaning is such that the zipper 13 containing Side surface 4 is directed vertically and that not the cover 10 adhering free edge 114 of the cover strip 110 is used for cleaning Liquid such as water through the cover strip 110 from the Filling opening 12 are kept away. The water that otherwise could reach the filling opening 12 now flows on the Outside of the cover strip 110. To the shielding effect of the cover strip 110 after Possibility to promote extends the free edge 114 of the Cover strip 110 preferably adheres as far as possible the zipper 13 over, preferably to the end of the relevant side surface 4 of the mattress 100.

    Mit den oben beschriebenen Maßnahmen ist die wichtigste Quelle für Flüssigkeitsinfiltration in die Matratze 100 beseitigt worden. Noch immer könnte aber Flüssigkeit über den für die Steppnähte 11 verwendeten Steppfaden kapillar angesaugt werden, obwohl die Menge der auf diese Weise eindringenden Flüssigkeit erheblich niedriger ist als bei Infiltration über den Reißverschluß 13. Gemäß einem anderen Aspekt der vorliegenden Erfindung wird auch diese Quelle für Flüssigkeitsinfiltration in die Matratze 100 beseitigt, wenn auch die Verbindungsnaht 130 wasserdicht ausgeführt ist.With the measures described above is the most important Source of liquid infiltration into mattress 100 been eliminated. However, liquid could still be over the capillary used for the stitching 11 capillary to be sucked in, though the amount of this way penetrating liquid is significantly lower than at Infiltration via the zipper 13. According to another Aspect of the present invention is also this source for Liquid infiltration in the mattress 100 eliminated if the connecting seam 130 is also watertight.

    Das kann beispielsweise bewirkt werden, wenn über eine Steppnaht, wie die Naht 11, ein in der Figur nicht dargestellter Nahtabdeckstreifen angebracht wird, der mit dem schon besprochenen Abdeckstreifen 110 vergleichbar ist. Dieser Nahtabdeckstreifen kann dann über seine ganze Oberfläche mit dem Überzug 10 verleimt oder verschweißt sein. Eine derartige Lösung hat den Vorteil, daß diese bei schon bestehenden Matratzen angewendet werden kann.This can be done, for example, when using a Quilting, like seam 11, is not shown in the figure shown seam cover strip is attached, with the cover strip 110 already discussed is comparable. This seam cover strip can then over its whole Surface glued or welded to the coating 10 his. Such a solution has the advantage that this existing mattresses can be used.

    Bevorzugt aber ist die Verbindungsnaht 130 selbst als Schweißnaht ausgeführt.However, the connecting seam 130 itself is preferred as Welded.

    Es wird dem Fachmann klar sein, daß es möglich ist, die dargestellte Ausführungsform der erfindungsgemäßen Vorrichtung zu ändern oder zu modifizieren, ohne den Erfindungsgedanken oder den Schutzumfang zu verlassen. So ist es beispielsweise möglich, daß über den Reißverschluß zwei Abdeckstreifen übereinander angeordnet werden, wobei die freien Ränder dieser zwei Abdeckstreifen entgegengesetzt gerichtet sind.It will be clear to those skilled in the art that it is possible to use the illustrated embodiment of the invention Change or modify the device without the Inventive ideas or to leave the scope of protection. So it is possible, for example, that the zipper two cover strips are arranged one above the other, whereby the free edges of these two cover strips opposed are directed.

    Auch ist es möglich, daß der freie Randteil des Abdeckstreifens sich über dessen Langseite befindet. Dabei braucht dieser freie Randteil sich nicht über die ganze Länge dieser Langseite zu erstrecken. Die Matratze könnte dann in liegender Stellung gewaschen werden. Diese Lösung ist jedoch weniger günstig, da der Abstand vom freien Randteil des Abdeckstreifens zum Reißverschluß dann kleiner sein wird, als bei der unter Hinweis auf die Figuren besprochenen bevorzugten Ausführungsform möglich ist.It is also possible that the free edge part of the Cover strip is located over the long side. there this free edge part does not need to cover the whole To extend the length of this long side. The mattress could then be washed in a lying position. This solution is less favorable, however, because the distance from the free Edge part of the cover strip for the zipper then smaller will be as when referring to the figures discussed preferred embodiment is possible.

    Weiter wird es klar sein, daß die Matratze 100 beim Waschen nicht derart orientiert zu sein braucht, daß der Abdeckstreifen 110 genau vertikal gerichtet ist, obwohl das bevorzugt wird. Tatsächlich ist jede Orientierung der Matratze 100, wobei das Wasser wenigstens nicht über den freien Rand 114 und den Kanal 120 die Öffnung 12 erreicht, eine geeignete Orientierung.It will also be clear that the mattress 100 when Washing need not be so oriented that the Cover strip 110 is directed exactly vertically, although that is preferred. In fact, every orientation is the Mattress 100, the water at least not over the free edge 114 and channel 120 reaches opening 12, an appropriate orientation.
